The long-range echo detection capabilities of echolocating bats (E. fuscus) were studied in a 2-choice psychophysical procedure. E. fuscus can detect 4.8 mm diameter spheres at a distance of 2.9 m, and 19.1 mm diameter spheres at a distance of 5.1 m. The threshold of echo detection corresponds to the distance at which a target returns an echo amplitude in the region of 0 dB SPL [sound pressure level]. Apparently, the maximum effective range of bat sonar is greater than previously indicated by obstacle avoidance and target-interception tasks.
